Could a 3D scanner replace the dental plaque check?
NCT ID NCT07152314
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests whether a 3D intraoral scanner can accurately measure dental plaque compared to the traditional method of applying a dye and visually scoring. Twenty adults with at least 20 natural teeth and visible plaque will be scanned before and after plaque disclosure and after brushing. The goal is to see if the digital method matches the standard clinical plaque index.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- intraoral scanner imaging
- What this could lead to
- If successful, this could provide a faster, more objective way to measure dental plaque, potentially improving diagnosis and monitoring of gum disease.
- What could go wrong
- This is a small, early-stage study with only 20 participants. The digital method may not prove accurate enough to replace traditional plaque scoring, and results may not apply to everyone.
